摘　　要：目的探讨轴内脑肿瘤的CT诊断价值，并分析其影响因素。方法2011年1月至2014年6月滨州市中心医院脑外科共收治66例轴内脑肿瘤患者，对其临床资料进行回顾性分析，以探讨分析其临床CT诊断价值及诊断的影响因素。结果本研究66例患者中胶质瘤、转移瘤、髓母细胞瘤具有较高的发生率，其中胶质瘤发病率为53．O％（53／66），其临床诊断正确率为82．3％（29／35）；转移瘤发病率为36．4％（24／66），其临床诊断正确率为95．8％（23／24）；髓母细胞瘤发病率为7．6％（5／66），其临床诊断率正确率为100％（5／5），各组间疾病发病率以及疾病诊断正确率比较差异均未见统计学意义（P〉0．05）。本研究相关因素分析发现，患者的年龄、肿瘤位置、肿瘤水肿、占位效应以及强化强度与肿瘤的CT诊断结果具有相关性（P〈0．05），为CT诊断的影响因素。结论脑肿瘤的CT诊断与肿瘤病变的CT特征（如肿瘤的位置、水肿程度、占位效应以及强化强度）以及患者年龄密切相关，临床诊断需要科学严谨的鉴别，防止误诊的发生。Objective To investigate the diagnostic value of CT in intra-axial brain tumors, and analyze the various influencing factors of CT in intra-axial brain tumors. Methods The clinical data of 66 cases of intra-axial brain tumors diagnosed in Binzhou central hospital from January 2011 to June 2014 were retrospectively analyzed. Results The gliomas, metastatic tumor and medulloblastoma had high incidence in the 66 cases of patients. The incidence of gliomas was 53.0% （53/66）, the cor- rected diagnosis clinical rate of gliomas was 82.3% （ 29/35 ）. The incidence of metastatic tumor was 36. 4% （24/66）, the corrected diagnosis clinical rate of metastatic tumor was 95.8% （23/24）. The in- cidence of medulloblastoma was 7.6% （5/66）, and the corrected diagnosis clinical rate of medulloblas- toma was 100% （5/5）. The right disease incidence and disease diagnosis accuracy had no significant difference （P 〉 0. 05 ）. In the analysis of relevant factors, the patient＇ s age, tumor location, tumor ede- ma, placeholder effect and strengthen showed correlation with the CT diagnosis of tumor （ P 〈 0.05 ）, which were the influence factors for CT diagnosis. Conclusions The CT features of tumor （ such as the location of the tumor, the degree of edema, placeholder effect and strengthen the intensity） and the age of patients are closely related to the CT diagnosis of tumor, which should be scientific and rigovous in the clinical identification of tumor to prevent the occurrence of misdiagnosis.
